Triggering of eruptions at Axial Seamount, Juan de Fuca Ridge. [PDF]

open access: yesSci Rep, 2020
AbstractThe submarine volcano Axial Seamount has exhibited an inflation predictable eruption cycle, which allowed for the successful forecast of its 2015 eruption. However, the exact triggering mechanism of its eruptions remains ambiguous. The inflation predictable eruption pattern suggests a magma reservoir pressure threshold at which eruptions occur,

The genome of a vestimentiferan tubeworm (Ridgeia piscesae) provides insights into its adaptation to a deep-sea environment [PDF]

open access: yesBMC Genomics, 2023
Background Vestimentifera (Polychaeta, Siboglinidae) is a taxon of deep-sea worm-like animals living in deep-sea hydrothermal vents, cold seeps, and organic falls.

Microbiological characterization of post-eruption "snowblower" vents at Axial Seamount, Juan de Fuca Ridge [PDF]

open access: yesFrontiers in Microbiology, 2013
Microbial processes within the subseafloor can be examined during the ephemeral and uncommonly observed phenomena known as snowblower venting. Snowblowers are characterized by the large quantity of white floc that is expelled from the seafloor following ...

A Diverse Community of Metal(loid) Oxide Respiring Bacteria Is Associated with Tube Worms in the Vicinity of the Juan de Fuca Ridge Black Smoker Field. [PDF]

open access: yesPLoS ONE, 2016
Epibiotic bacteria associated with tube worms living in the vicinity of deep sea hydrothermal vents of the Juan de Fuca Ridge in the Pacific Ocean were investigated for the ability to respire anaerobically on tellurite, tellurate, selenite, selenate ...

Temperature and redox effect on mineral colonization in Juan de Fuca Ridge flank subsurface crustal fluids [PDF]

open access: yesFrontiers in Microbiology, 2016
To examine microbe-mineral interactions in subsurface oceanic crust, we evaluated microbial colonization on crustal minerals that were incubated in borehole fluids for one year at the seafloor wellhead of a crustal borehole observatory (IODP Hole U1301A,

Influence of Igneous Basement on Deep Sediment Microbial Diversity on the Eastern Juan de Fuca Ridge Flank [PDF]

open access: yesFrontiers in Microbiology, 2017
Microbial communities living in deeply buried sediment may be adapted to long-term energy limitation as they are removed from new detrital energy inputs for thousands to millions of years.

Distribution of methane-cycling archaea in buried ridge flank sediment: community zonation, activity, and potential environmental drivers [PDF]

open access: yesFrontiers in Microbiology
Subseafloor sediments harbor Earth’s biggest reservoir of methane, with most of this methane being produced biologically by methanogenic archaea (methanogens).

Genomics discovery of giant fungal viruses from subsurface oceanic crustal fluids [PDF]

open access: yesISME Communications, 2023
The oceanic igneous crust is a vast reservoir for microbial life, dominated by diverse and active bacteria, archaea, and fungi. Archaeal and bacterial viruses were previously detected in oceanic crustal fluids at the Juan de Fuca Ridge (JdFR).

Phylogenetic diversity of microorganisms in subseafloor crustal fluids from boreholes 1025C and 1026B along the Juan de Fuca Ridge flank [PDF]

open access: yesFrontiers in Microbiology, 2014
To expand investigations into the phylogenetic diversity of microorganisms inhabiting the subseafloor biosphere, basalt-hosted crustal fluids were sampled from Circulation Obviation Retrofit Kits affixed to Holes 1025C and 1026B along the Juan de Fuca ...

First shotgun metagenomics study of Juan de Fuca deep-sea sediments reveals distinct microbial communities above, within, between, and below sulfate methane transition zones [PDF]

open access: yesFrontiers in Microbiology, 2023
The marine deep subsurface is home to a vast microbial ecosystem, affecting biogeochemical cycles on a global scale. One of the better-studied deep biospheres is the Juan de Fuca (JdF) Ridge, where hydrothermal fluid introduces oxidants into the sediment
